Google Finance is a website launched on March 21, 2006 by Google. The service features business and enterprise headlines for many corporations including their financial decisions and major news events. Stock information is available, as are Adobe Flash-based stock price charts. The site also aggregates Google News and Google Blog Search articles about each corporation, though links are not screened and often deemed untrustworthy.[1] Google added advertising to its finance page on November 18, 2008. Until this time, it was free of advertisements.

Google launched a revamped version of their finance site on December 12, 2006, featuring a new homepage design which lets users see currency information, sector performance for the U.S. market and a listing of top market movers along with the relevant and important news of the day. A top movers section was also added, based on popularity determined by Google Trends. The upgrade also featured charts containing up to 40 years of data for U.S.stocks, and richer portfolio options. Another update brought real-time ticker updates for stocks to the site, as both NASDAQ and the New York Stock Exchange partnered with Google in June 2008.[2][3]
